I need to perform a complex mapping between "old style" structured identifiers and "new style" structured identifers. As the original specification was never thought through or written down anywhere, I'm now having to try and reverse- engineer from 5 years of collected inconsistent practice. So far I have about four pages of BNF to describe things and I'm still not sure what's accurate, what's inaccurate spec and what's merely an error in practice. Hopefully there's a neat little structure underlying it all and a few typos I can merely ignore, but probably it really is just an inconsistent structure that needs a lot of explicit tests around the corner-cases to make sense of. rot13 isn't the issue here, and I already know how to use .translate() What I'm after is a tutorial of my Python coding style for an example that's quite similar to the rot13 case. Your previous posting was very helpful here. -- http://mail.python.org/mailman/listinfo/python-list
